The Company also incurred $3 million in Facility Closing Costs related to a lease termination settlement.

The streamlining of the field operations model, which was announced in fiscal 2015, resulted in a restructuring charge of $20 million, consisting primarily of Severance and Related Costs.

The Baltimore, Maryland distribution facility was closed during 2016, and the Company incurred $15 million of costs associated with the closure activities. In addition, the Company settled its fiscal 2015 estimated pension withdrawal liabilities associated with the Baltimore facility, and realized a benefit of $4 million.

During the Company’s fourth quarter 2016, the Company announced its plan to streamline its corporate back office organization, and centralize certain replenishment activities, and incurred restructuring charges of $13 million and $7 million, respectively, consisting primarily of Severance and Related Costs.

At December 31, 2016, Severance and Related Costs primarily consisted of $3 million, $11 million and $7 million related to the Company’s field reorganization, corporate reorganization, and replenishment centralization initiatives, respectively.

2015 Activities

During fiscal year 2015, the Company incurred a net charge of $172 million primarily for Severance and Related Costs related to the field reorganization, closure of the Baltimore, Maryland facility and settlement of the Central States Teamsters Union Pension Plan (“Central States”) described below.

In December 2015, the Company reached a settlement with Central States as discussed in Note 17, Retirement Plans. The settlement relieved the Company’s participation in the “legacy” pool and settled the related legacy multiemployer pension withdrawal liability, and commenced the Company as a new employer in the “hybrid” pool of the Central States Teamsters Southeast and Southwest Area Pension Fund (“Central States Plan”). The payment also included the settlement of certain other Central States multiemployer pension withdrawal liabilities relating to facilities closed prior to 2015, and the related Eagan, Minnesota labor dispute. The settlement resulted in a restructuring charge of $88 million.
